LEF-300 Scuffing

Post by joe4sho » Thu May 31, 2018 2:18 pm

Good morning, seems like alot of helpful people on here so I thought I would give this a shot. I am having an issue printing white to cover the layer of cmyk to make it pop. It looks as if there is colored ink dragging through the print or the heads or something is touching. I have done manual cleaning to see if there was debri rubbing and medium head cleaning through the machine. I want to rule out the heads hitting because the auto detect on the table height should have had adjusted to the highest point of the material correct? Anyways I have attached images so hopefully someone here knows how to help me out. Thanks in advance!

Did you also clean the rest of the carriage infrastructure when making manual cleaning? It may be something dangling from the UV lamp or other moving parts of the carriage.

Seems like it may be a humidity and static problem after watching it print. Any resources out there to eleviate static internally in the printer? I am going to try to get the humidity up into range in the meantime. Thank You.

This should vary media by media. Does it.

Can use an anti-static cleaner before printing.
Also could change the auto-down in the menu. Does the material bunch up when printing-even if only a little bit?

It only does it on this media but I have printed it fine before. It does not bunch up at all it is a rigid piece of acrylic 1/8". After another print this morning and another setting I am finding that it is not dust causing this it is actually spurts of ink and them getting dragged across the material. Has this happened to anyone?

Try printing in "distance mode" with a slower carriage speed. Static would affect this as well, equally, other mechanical issues should change the result.

I print onto acrylic myself, are you clamping down? Is the material bowed? I wipe each piece with IPA and a microfibre cloth prior to printing as static can be a problem on acrylic.

I use IPA with a lint free cloth to clean, the material is not bowed but there is no way to clamp it down anyway even if it was
